Math Table


Math Table is a seminar jointly run by the Harvard Mathematics department and undergraduate students. The purpose of Math Table is to provide an opportunity for undergraduates to be exposed to interesting mathematical topics, as well as to gain experience in communicating and teaching mathematics.

Talks take place in Science Center 232 every Tuesday at 5:30 PM. Talks are catered, with different kinds of food every week. We do our best to accommodate all dietary needs, so if you have any concerns please send us an email in advance (see "About" tab for contacts).

Who can attend/give talks?

All Harvard undergraduate students are welcome to attend any Math Table talk and to sign up to give a talk. Talks come in a wide array of topics, background levels, and styles (see the "Resources" tab). The Math Table organizers (see "About" tab) are here to help you pick topics and develop your talk, so even if you aren't sure about what your topic is, you should come speak with us!

To sign up to give a talk, or if you have any questions about Math Table, please send an email to and/or, or to any of our undergraduate coordinators (see "About" tab for contacts).

Math Department Round Table

Come on by to share and learn what Harvard students have done with math outside their classes, such as REUs, internships, and other research.

Recent Talks

Tuesday, Sep 18 (5:30pm, SC 232)

Speaker: Sebastian Vasey

Title: Hypercomputation

Abstract: David Hilbert's "Entscheidungsproblem" asks for an algorithm to prove or disprove any mathematical statement. The non-existence of such an algorithm was proven independently by Church and Turing. This is often interpreted as meaning that there is no streamlined method to prove something: it takes hard work and creativity... Or does it? What did Church and Turing precisely prove? Could we imagine a hypercomputer capable of performing infinitely-many steps in a finite time? Could we build such a machine, or at least come close? I will discuss these questions and more.

Tuesday, Sep 11 (5:30pm, SC 232)

Speaker: Davis Lazowski

Title: Quiver Representations

Abstract: Quiver representations give a beautiful, pictorial way to encode algebraic data. In this talk, the speaker will introduce quiver representations and study simple examples. At the end, the speaker will briefly survey applications to Lie theory and algebraic topology. The talk assumes some knowledge of linear algebra.

Tuesday, Sep 4 (5:30pm, SC 232)

Speaker: Cliff Taubes

Title: Mysteries of 4 Dimensions

Abstract: The classification of spaces of dimensions 1-3 and 5—∞ is well understood. Dimension 4 is not understood. In fact, there are no compelling conjectures as to what the answer should be. I hope to explain some of this in the talk.

At 5:00pm in the same room, Gabriel Goldberg will be giving an overview of his fall tutorial "Infinite Combinatorics".
